Patented Apr. il?, 11917.

Application led May 1, 1913. Serial No. 764,849.

objects of this invention are to reduce the Weight of the machine,increase the traction of the main wheel and reduce the draft in such amanner as to provide a. comparatively light machine of compact andrugged construction whichA is adapted to perform economical andefiicient service under varying conditions.v These objects are attainedby ani improved combination of the several mechanisms compri-sing themachine and by specific improvements in the machine frame, the conveyermechanism and the threshing and separating mechanism, as well as themeans for operatively "connecting, driving and adjusting thesemechanisms.

In order that this invention may be clearly and fully disclosed,oneembodiment thereof is shown in the accompanying drawings. It is to beunderstood, however, that the form chosen for purposes of illustrationmay be modified without departing from the spirit of the invention.

The construction shown, when broadly considered, comprises a wheeledframe, cutting apparatus disposed transversely there of and of the lineof draft, conveyer mechanism receiving the grain cut by the cuttingapparatus and delivering the same in a rearward direction substantiallyat right angles to the cutting apparatus, threshing mechanis'm carriedon the frame between the main Lwheel thereof and the side transportwheel receiving the grain from said conveyer mechanlsm, and separatormechamsm coperating with said thresher mechanism and locatedsubstantially beneath the rearwardly extending straw racks of thelatter; the several mechanisms of the machine being of an improvedconstruction and operatively connected, controlled and adjusted in animproved manner hereinafter described.

In order ,that the relation of the several parts of the mechanism intheir respective locations may be more clearly understood, the frame ortruck of the machine will first be described.

The machine frame.

This frame is of the wheeled type and is adapted to be drawn by horses,trailed in the rear of a tractor, or used in tandem relation with othermachines.

lt is mounted upon a main wheel 1, a side transport wheel 2 parallelthereto and spaced apart therefrom, and a front wheeled truck 3 disposedsubstantially in front of the main wheel. As shown in Fig.. l, the mainwheel 1 and the transport wheel 2 are rotatably i mounted upon theopposite ends of a transversely disposed axle member 4. This axle memberis connected to the wheeled truck "3 by a plurality of longitudinallydisposed frame members 5 converging and rigidly connected together attheir front ends abov the tongue truck and disposed parallel to eachother at their rear ends on opposite -sides of the main wheel. As shown,this latter wheel is rotatable upon the axle 4 adjacent the stubblewardframe member 5 and between the same and a short rearwardly extendingframe member Gwhich is rigidly attached at its front end to a shorttransversely disposed brace or frame member 7 rigidly connected at itsopposite ends to the members 5 at points in front the main wheel. Asillustrated in Fig. 4, the

axle member 4 is journaled in suitable brackets 8 and 9 fixed theretoand to the frame members 5 and 6 respectively. A second transverse framemember l0 is also provided, the ends of which are bent forward andrearward respectively at an angle and rigidly attached to the brace 7and a bracket ,11 fixed to the axle member 4 at a point adjacent thetransport wheel 2.

A supplemental frame, cutter frame or grain platform for the heading orcutting apparatus is pivoted upon the axle member 4 near its ends andbowed intermediate their ends and rigidly connected together by a bolt15 at the point where the member 14 crosses the member 13; As shown, thefront ends of these two members underlie the frame 12 and are rigidlyconnected thereto at a plurality of points between `its ends. The rearend of the member 13 is attached at 16 to a bracket 17 rotatably mountedon thev axle member 4 adjacent the stubbleward side of the transportwheel 2 and preferably provided with a flange 18 inclosing the end ofthe wheel hub. The rear end of the member 14, however, is rigidlyattached at 19 to the rear end of a longitudinally disposed support 20rigidly attached at its front end to the stubbleward end of the frame 12and at its rear end attached to a depending bracket member 21 journaledupon the axle member 4 at a point between the frame member 6 and thegrainward frame member 5. A fourth diagonally disposed support or brace22 is attached at its front end to the grainward end of the frame 12 insubstantially the same manner as the members 13 and 14, and is attachedat23 to a bracket 24 of similar construction to the bracket 17,rotatably mounted on the grainward end of the axle member 4 and on theopposite side of the transport wheel 2 from the bracket 17. It is to benoted that the frame thus provided to carry the cutting mechanism ismovable about the axle mem-- ber 4 as a pivot so that the height of itsfront end from the ground may be varied by the manipulation of adjustingmechanism hereinafter described. It is further to be noted that theframe, while so adjustable, is

lat the same time so rigidly bracedy and connected as to provide anexceedingly rugged and rigid construction.

The frame for the threshing and separatingmechanism is likewise carriedupon the axle member 4 and located between the main wheel 1 and thetransport wheel 2. This frame is disposed longitudinally as shown inFig. 1 in substantially the same plane as the frame members 5 and 6, andcomprises a longitudinally disposed frame member 25 rigidly supported atits front end on the transverse frame member 10 and at a pointintermediate its ends supported by a bracket 26 carried on the axlemember 4. As shown, the frame mem- .ber 25 and the grainward framemember 5 are protruded rearward beyond the end of the stubbleward grainmember 5 substantially parallel to each other in such a manner as toform a support'for the threshing and separating mechanism. In Vorderthat this mechanism may be carried close y to the ground to afford acompact construction adapted to use on uneven ground, Vthe axle member 4is bowed intermediate its ends into substantially U shape as shown at27, and the brackets 8 and 26 are so shapedv as to conform to thecurvature thereof. VIn order to provide a rigid support, the axle member4 is also braced by a substantially U-shaped truss or channel 28 whichextends under the bowed portion of the member 4 and is attached at itsends to the brackets 9 and 11 and itself provided with brackets 29, 30in which are seated the lower rounded shoulders of the axle member.Further rigidity of the parts is obtained by attaching the severalbracket members to the axle member by suitable flat U-bolt connections31, 32.

Upon the frame thus formed the heading or cutting apparatus and the-threshing and separating mechanisms are carried.

these mechanisms we will first consider the This apparatus is carriedupon the frame 12 and disposed transversely to the line of draft in sucha manner that it cuts the grain as the machine is drawn forward.

It comprises a knife bar v34 reciprocable across the front edge of theframe between the guard fingers 35 carried thereon. This knife isoperatively connected through a pitman connection 36 with a sprocket 37carried on the end of a power .shaft 38 driven from the main wheel. Asshown in Fig. 1, this shaft is journaled in suitable bearings 39 carriedupon the stubbleward end of the frame 12 and is disposed parallel to theline of draft; the front end of the same being disposed parallel to theground and connected through a universal joint 4() and an extensibleconnection 41 with an upwardly extending` portion thereof. As shown inFig. 1, this shaft is operatively connected through beveled gears 42,43, carried in a gear casing 44 journaled in theframe, to a transverselydisposed shaft 45 which is in turn driven by a pinion 46 meshing with aninternal gear 47 on a larger gear 48 likewise journaled on the frame andcarried `upon a stub shaft 49 at the rear ofthe shaft 45 and parallelthereto. Upon the stubbleward end of this stub shaft 49 is carried asimilar pinion 50 which meshes with an internal gear 51 upon the mainwheel 1 and upon manipulation of a controlling lever 52, normally heldunder pressure by means of a spring 53 and pivotally mounted upon abracket 54 .carried upon the frame, is movable into or lili inmenso andis so disposed with respect to the cutting 'i mechanism that itoperatesupon the grain Ain the usual manner. This reel is 'carried upon asuitable shaft 57 mounted ina well known manner in bearings 58,-only oneof which is shown, and is also operatively connected to the main wheelthrough the power shaft 38. This connection is shown in Figs. l and 2 tocomprise a sprocket and chain connection 59 extending between a sprocket60 on the stubbleward end of the reel shaft 57 and a small sprocket 61carried upon a stub shaft 62 journaled in the frame 12 at a pointintermediate the ends of the horizontal portion of the power shaft 38and disposed at right angles thereto. As shown in these figures, thisshaft 62 also carries a pinion 63 adjacent the sprocket 61, and thispinion is provided with a beveled gear 64 on its outer face which mesheswith a corresponding gear 65 carried on the shaft 38. llt is thusseenthat as the shaft 38 is rotated, the rotation of the same istransmitted to the reel through the beveled gear connection 64, 65 andthe sprocket and chain connection 59, 60, 61. As in the case of thecutting mechanism, the reel is also controlled by the lever 52.Obviously, if desired, in order to suitably brace the reel support, asuitable longitudinally disposed stay or stays 66 may be providedbetween the reel supports and the rear of the frame 12. i

Coperating with the cutting mechanism is a conveyer mechanism which, asit is cut, feeds the grain transversely and then rearwardly.

The conveyer mechanism.

The conveyer 68 is disposed at right angles to the conveyer 67 andbeneath the stubbleward end thereof, and is shorter than the latter. Asshown in Fig. 1, it is carried on rollers 74 journaled in the frame 12and spaced extensions 75 protrudingy rearward from the stubbleward endthereof. This apron is likewise driven from the power shaft 38, a pinion76 being provided on the the thresher.

stubbleward end of the front roller shaft which meshes with the teeth ofthe pinion 63 and is driven by the latter in such a manner that when theshaft 38 is rotated the conveyer 68 moves toward the rear, feeding thegrain delivered to it by the conveyer 67 in a rearward direction.

Coperating with the conveyer 68 are the superimposed thresher feedingconveyers 69 and 70. As shown in Fig. 2, these two con# veyers arepivotally mountedupon shafts 77 and 78 journaled in the thresher frame79 at points above the conveyer 68 and at the rear thereof; the twoconveyers being carried in frames 80 and 81 which protrude 'downwardfrom their pivots on the shafts 77,

78 into such a relation with the conveyer 68 that the grain fed rearwardthereby is fed upward by the two conveyers 69 and 70. As shown, theconveyer 70 is mounted upon suitable rollers 82, 83 of differentdiameters journaled in the frame 81 and this conveyer is longer than theconveyer 69, protruding beneath the rear end of the conveyer 68. Theshorter conveyer 69 is mounted upon rollers 84, 85 and 86 and extendspart way down the conveyer 70, into contact therewith at a pointadjacent the upper end of the latter, and beyond this end, the roller 85of the conveyer 69 being smaller than the other rollers and acting as anidler, while the roller 86 thereof is located substantially in rear ofthe roller 85 so that the delivery end of the upper conveyer isangularly disposed with respect to the lower conveyer and brought intocloser proximity to As shown, the two conveyer frames 80 and 81 are alsoconnected by links 87 which hold the lower end of the conveyer 69 awayfrom the surface of the conveyer 70, thereby causing that end to beangularly disposed with respect to that conveyer, yet per mitting theconveyer 69 to rise and fall independently of the conveyer 7 0. Both ofthese conveyers are preferably driven at the same speed throughintermeshing pinions 88, 89carried on the stubbleward ends of the shafts77, 78 respectively and driven through a sprocket. 90 (on the end of theshaft 78) and a chain 91. This chain 91 is driven by a sprocket 92carried upon a stub shaft 93 journaled in the frame on brackets 94 andthis sprocket 92 is driven through a pinion 95 xed to the shaft 33 andmeshing with the gear 48 heretofore described.

The supplemental frame 12 carrying the cutting apparatus, the reel andthe conveyers 67, 68, is, as heretofore described. movable about theaxle member 4 as a pivot through improved adjusting mechanism.

Tw cutter frame adjusting mechanism..

This mechanism is operated from a horizontally disposed platform 96carried on the frame members 5 atra point in front of the main wheel andadjacent the operators seat 97.

It comprises a vertically extending lever 98 pivoted to the frame at 99and connected at 100 to a rearwardly extending link 101. This link ispivoted at its rear end to anupstanding arm 102 on a transverselydisposed member 103 journaled in suitable bearings 104 on the platform96 and provided with a forwardly protruding arm 105 substantially atright angles to the portions 102, 103 and pivotally connected at 106 toa depending member 107 pivoted to the bottom of the frame 12 at a pointadjacent the stubble ward yend of the same. It is to be noted that bythe movement of the lever 98, the arm 102 is thrown about in itsbearings 104 in such a manner as to raise or lower the arm 105 andtransmit this movement to the member 107 to move the whole frame 12 andthe mechanism carried thereby about a pivot on the axle member 4. 1t isfurther to be noted that due to the lever connection employed, theamount of effort required to lift the arm and its mechanism ismaterially reduced, and that a pair of springs 108 interposed betweenthe frame 12 and a bracket 108 at the grainward end of the truss 28,(the latter braced on the frame member 25 by a brace 33), assist theoperator in the raising operation. Obviously, in order to hold the framein any desired position, a suitable segment and coperating detentmechanism 109 may be provided. l

Coperating with this adjusting mechanism and serving to maintain theconveyers 69 and 70 in the desired relation to each other in anyposition of the frame 12, is an improved sliding connection between therear end of the frame 12 and the conveyer frame 81. This connectioncomprises a plurality of elongated ways 110 disposed longitudinally ofthe fra-me 81 l`and attached thereto near its lower ends and on itsopposite sides, in which the rollers 111 journaled on the ends ofrearward extensions 112 on the frame 12, are movable when the latter isadjusted. It is to be noted in this connection that when the frame 12 ismoved upward or downward, the same is thus automatically maintained inthe desired relation to the conveyer frame 81 so that the grain fed outfrom the conveyer 68 is received by the conveyer the rollers 111 movinglongitudinally in the ways 110, as is clearly apparent from Fig. 2.

Due to the construction and arrangementy of the conveyers 69 and 70, thegrain is compressed and fed out evenly between the upf per ends of theseconveyers in a rearward direction directly to the cylinder of thethreshing mechanism.

The threshing mechanism. This mechanism is carried by the thresherthresher box and driven through a pinion 118 journaled on the end of itsshaft 119 and meshing with the gear 120 carried on the As shown in Fig.3, this cylinder is inclosed by a metallic casing 121 having a removablecover 122 which is pivoted at 123 to the thresher frame 79 and providedwith a iange 124 which extends to a point adjacent the surface of theapron 69. Coperating with this lid 122is a pivoted flap 125 carried on atransverse rod 126 journaled to the front end of th'e casing 121. Asshown, -the casing 121 extends down vertically on the opposite ends ofthe cylinder and carries a thresher'concave 127 which coperates with thecylinder in a well known manner, a liap 128 connecting the front end ofthis concave with the bottom of the frame 81, and a grate 129 beingattached to the rear endthereof.

The separator mechanism is disposed beneath this concave. As shown, aslanting deflector 130 is attached to the casing and beneath thisdeiiector is pivotallymounted a grain pan 131 having a slanting bed 132protruding under the deflector 1'30 and screens 133,134 spaced apartfrom the bottom thereof in such a manner as to separate the grain fromthe chad'as the same falls down upon the grain pan from the threshercylinder. As in the usual construction, a fan 135 is provided. This fanis carried on a shaft 136 j ournaled beneath the thresher cylinder andthe grain pan 131, and is driven through a sprocket 137 on the grainward`end of this shaft and a chain 138. This chain 138 is driven through asprocket 139 carried on the shaft 45 which is mounted in bearings 141 onthe frame member 10 and driven by the main wheel through gearingheretofore described. The grain pan '131 is `shaft 93 and driven fromthemain wheel.

likewise driven from this shaft 45 through a beveled gear 142 meshingwith teeth 143 upon the side of the sprocket 139 and carried upon theend of a longitudinally and downwardly disposed shaft 144 having a crank145 on its rear end which, When the shaft is rotated, imparts a rockingmovement in a lateral direction to the frame 131. As in the usualconstruction, the end of the grain pan 131 is open so that the draftfrom the fan 135 may blow out the chaff and'dirt from the rear of thesame as the grain passes between the screens.' As in the usualconstruction, a Weed screen 146 may be pro- Lazare@ vided beneath thescreen 134 and a suitable retarder 147 may be provided at the end of thesame. Further, as in the usual construction, the fan is in'closed in asuitable casing 148 which, in this' construction, is shown to besupported by braces 149 supported by the truss member 28 throughhorizontally disposed supports 150. These supports 150 may also be usedto support a wood seed box 151 at a point beneath the weed screen 146.

The straw rack mechanism is disposed adjacent the end of the grate 129and above the grain pan 131, and is mounted in the box 79. Thismechanism comprises a plurality of. straw racks which are operativelyconnected through ymultiple throw crank shafts 153 journaled at theirends in the box 79 and on the straw rack frame in bearings 154 anddriven through a sprocket and chain connection 155 from a sprocket 156on the shaft 93. Each of these straw racks preferably comprises a pairof parallel members 157 having a plurality of parallel slats 158disposed transversely thereof on an inclined portion of the samesubstantially beneath the grate 129. As the straw is fedout from thisgrate 129, it is kicked upward by the slats and deposited upon a screen159 having a plurality of perforations therein. From this screen it isthen fed rearwardly to a series of slatted portions 160, 161 alternatelydisposed horizontally and at an angle to the horizontal and so arrangedas'to kick the straw upward and flu the same out thoroughly before thesame is ejected through the open end of the box 79. 0bviously, due tothe provision of the multiple crank, the several racks will be given anorbital movement and will act successively upon the straw in such amanner as to fluff out the same and thoroughly separate the threshedgrain therefrom so that the latter will fall through the same upon thegrain pan 132. In order to prevent the cylinder `from discharging thestraw in an upward direction, 'a curved shield 162 is provided at therear of the same which extends down in the path 'of the straw dischargedfrom the cylinder and deects the same upon the straw racks,aflexibleflap 163 preferably being provided upon the lower end of thesame in order to lie close upon the straw and Ayet enable the latter tobe fed outward by the straw racks. v As shown 1n Fig.l 2, suitablerods164 may connect the box 79 and the grain pan box 131 and in order tofurther'suitably support the parts, the weed seed box 151 may beattached to the grain pan box 131 by suitable braces 165. v

As the unthreshed grain is separated from the chaff 'and the cleangrain, it is received in a transversely disposed slanting trough 166 (atthe rear end of the box 131 and substantially beneath the retarder 147)and by it is conducted to an elevator 167 which extends upward parallelYto the thresher box '79.to a point above the cylinder 114, where it 1sconnected through apipe 168 with the cylinder` chamber in such a manneras to return the tailings to the cylinder to be again acted upon by thethreshing mechanism. The threshed grain, on the other hand, is conductedfrom the frontend of the box 131 by a transversely disposed slantingtrough 169 and delivered to the elevator 170 which extends substantiallyparallel to the elevator 167 and may be provided with any suitable chuteconnection 171 adapted to use in bagging the grain, or conveying thesame to any suitable grain box carried upon the frame in a well knownmanner. As shown in Figs. 2 and 5, the conveying mechanism for each ofthese elevators 167, 170 is driven from the chain 91 which rotates apinion 172, journaled at the top of the conveyer 170, and through it anda piniona 173, drivesva chain and sprocket-connection 174 operativelyconnected to the elevatorV mechanism of the elevator 167. 1-

The operation of the construction shown is as follows: Let us` assumethat the machine is being drawn toward the grain. In order to set theseveralv mechanisms of the machine in motion, the operator throws thelever'52 about its pivot to throw inthe pinion 50. Through the gearingheretofore described,

each of the mechanisms in the machine is' then positively connected tothe main wheel. The knife bar is'being operated; the conveyers aremoving; the reel is rotating; the thresher cylinder is rotating; thestraw racks are moving through their orbital movement; the grain pan isbeing moved back and forth in a lateral direction; the fan is rotating;andthe grain and tailings elevators are operating, so that as the grainis cut ,it is threshed and separated, the clean grain being delivered atone point, while they straw and chaff are ejected at the rear parallelto the line of draft. Obviously, if the operator desires to adjust theheight of the cutting mechanism, this adjustment is readily accomplishedby manipulation of the lever 98. j

It is to be noted that in this construction the entire mechanism iscontrolled by a pair of. levers readily operable from the operatorsseat. It is further to be noted that the construction is exceedinglyrugged and that the While one embodiment of this invention has beendescribed herein, it is to be understood that the form chosen .forpurposes of illustration is susceptible of modification l by the formermay move bodily longitudinally of the latter.
